Although, sterling silver, coin silver, pure silver belong to silver item, the mean of them is different. Sterling silver is different from pure silver and coin silver. Coin silver is 90 percent pure silver and the remaining part consists of other metal. Usually, It is copper. Pure silver, referred to as fine silver, has the silver content of 99.9%. Pure silver is too soft to be used in jewelry making and be any other physical object. Therefore, pure silver need to mix with other metal to make it strength and hardness. Sterling silver, called 925 sterling silver in China, is an alloy of at least 92.5% silver and 7.5% other metal add it. The metal used in sterling silver include zinc, germanium, platinum, silicon, copper and so on.
Most sterling silver is made up with pure silver and copper. Copper can maintain the silvery color of the alloy while improve its durable.

A silver jewelry labeled them you buy means genuine sterling silver jewelry. Coin silver is marked with “coin silver”,”coin”,”900”,”.900”,or”90” which mean the piece has at least 90% of pure silver. Pure silver is stamped with “999” means high purity silver. But, the silver jewelry marked the number of 925 don’t really has pure silver content of 92.5% in somewhere. In other words, some fake sterling silver jewelry is sold in the market.
